I have turned off Always on display almost 2 weeks ago, but when I check the other day, the darn thing is using 430 MB of RAM.
Anyone else is seeing the same behavior?

mine is 119MB memory used and my Always on display has been off for a few months.

And since I was messing around in the App info for Always On display, it went up to 120 MB memory used.

Even though I was just clearing data/cache. So that's weird.

Storage is the 1 you should worry ..
Do device maintenance and clear the cache partition once in awhile .
Android system or any os system will use memory off and on to operate ,
It does not hold ....
Have you ever seen it says ... "Out of Memory" ... ?
Cheers ...:)

It's not "using" RAM, it's "occupying" RAM. Because Android hasn't needed that RAM for anything else, so it never killed it. Read Multitasking the Android Way, by one of the designers of Android, to learn how Android works. As long as you aren't running short of RAM (and these days, that's just about impossible), Android will keep as much that you might use in RAM.

@Abbers:
"Doing things" needs more RAM, so it's not weird. Data and cache reside in storage, not in RAM. Clearing them takes RAM. Then, since Android doesn't need the RAM, it doesn't kill the app. (It doesn't matter - the app isn't running, so it's not using battery. "Closing" an app by hitting the home button, on the other hand, leave the app running, eating battery. The Back button closes the app, like hitting the X in a program in a PC. That's still in RAM too, but it stops running.)

@Rukbat, does not compute.
You are talking about apps that are enabled and were ran in the recent past. And you are right.
I am talking about an app that is turned off since a long time ago, the phone has been rebooted several times since then, yet it is using almost half a gigabyte of RAM.
For example, tonight it is using 268 MB.
I am saying "using" because the phone says "AVERAGE MEMORY USAGE" if you press Memory for details.
The phone is stock, without any modifications whatsoever. No picture on AOD.

Botton line is : you have nothing to worry ..
Androud know what to do with those ram..
For instance :
If you run a heavy game , It will take back all those Idled ram ..
Worst case is that game will slow down .. that's all.
